Someone may have requested this else where but I could see a necessity for a remote, maybe wifi slave unit that can report to the main RA controller for people to monitor and control additional tanks with a single controller. Many people in the hobby have more then one tank and even the ability to monitor a few basic things on other tanks would be useful. I have a client with one show tank and seven other smaller tanks. There is no way I could sell him on 8 units but perhaps one unit for his show tank and several other remote modules to even monitor the smaller tanks.
